Mold cost ranges from about $3,000 for simple molds, per Icomold, to $100,000 or more for hardened steel production tools, per Linton’s rapid molding guide. A $20,000 tool adds $2.00 to each […]

Key Takeaways Design for manufacturing (DFM) is not a final engineering check. Cost, materials, process, tooling, tolerance, and appearance are linked from the first design decision, and treating DFM as a late gate is how expensive tooling and unsourceable materials get locked in.

Key Takeaways AQL (Acceptable Quality Level, or Acceptance Quality Limit) is an acceptance-sampling standard used to determine whether a production lot meets an agreed quality threshold by inspecting a sample rather than every unit. The sample size and accept/reject numbers come from standardized tables in ANSI/ASQ Z1.4 and ISO 2859-1, not from the factory’s judgment […]

Key Takeaways Contract manufacturing in China works when a product has finished specifications, a realistic order volume, and defined quality standards, and becomes risky without them Vetting a factory means more than checking a business license. It requires a physical or remote audit and a pilot run measured against written acceptance criteria IP protection comes […]
